I'm fortunate, I've reached my third decade and don't have to worry too much about shaving - blessed with being blonde and slow growing hair-wise. I can leave it a week and have less stubble than some of my mates get in a day, but it does become a porn muzzy and half a goatee so it gets shaved fairly regularly, but strictly to keep it looking acceptable - I have no interest in having " a look" or being fashionable - I just dislike having fur but dislike shaving it more. Sometimes I'll part shave it just because a full shave will be a pain in the bum and too time consuming. God by the time it reaches about 5mm long it's tickling the hell out of my face, catches on everything, catches everything and makes me look like a tramp.
A strong jawline looks much worse shaved:
What if you like a strong jaw line? Surely it looks much better shaved then?
